Have had two of these for a few years now and have used them primarily as compact pa systems with an acoustic guitar and vocal mic. Works very well for dinner music, with the balanced mic input in channel two and the effects are just enough for a little ambience without having to bring in anything other than instrument, mic, stand and amp - one quick trip.

Over the last few yeas I've had to call Acoustic Image only a couple of times and always had the phone answered very quickly, and had all my questions answered. Excellent design, customer service and manufacture quality. Even on such a tiny unit, SpeakOn connectors and heavy duty speaker cable.

For bass I find the tone to be quick and punchy, even at whisper quiet practice levels and makes low level practice much more enjoyable than any other amp that you would normally have in the bedroom with you.

Very easy to use, logical control layout and while I wish there was a bit more range on the tone controls, they sound good right out of the box with all controls flat.

My take on these tiny combos is that they are a perfect amp for small, low level gigs, compact all-in-one sound systems and elegant practice amp that doesn't look out of place, or take up much space around the house. Add a 2x10 or 4x10 and you could probably play it on any stage.

Ive played SWR , Ampeg , Eden , Ebs and others , big rigs with 410 speakers and 810 speakers , for thoose amps you need a roadie .. I would say this amp gives me enough power to replace thoose big rigs , but its ten times smaller !

For gigs , i just take the amp on my shoulder and i roll my upright with the other hand .. i can now walk to my local gigs !

About the sound , its just amazing ..
The tone is rich and goosy , sounds a bit like a tube amp but still with a very hitech distinct sound . It gives me a perfect hitech sound for my electric basses (passive Fenders) with a nice low and a very sharp mid , though the Eq is very sensitiv and it takes som time to master .

For my upright it gives me a tight and very "electric sound" , almost like a fretless bass guitar. I use a Fishman dual piezzo pickup , if i have the "brite" on 75 % and then i cut the "treble" to 0% , wich gives a very nice sound for reference , distinct and tight .

I think its sounds a bit like a WW , with the acoustic tone , it realy makes the upright sound like an upright , sometimes the normal amplifiers takes away the acoustic soul in the instrument , but not the AI amplifier.

Now in thinking of buying a Focus ll R , and two EBS neo cabs ..

(obs , i use the first model , with the old design , but its the same amp)
